A much better method is to raise the forearm while turning the rod hand inward and down. Before the cast, the elbow should be even with or higher than the head, with the rod hand well below the chin. The thumb is behind the handle, away from the direction you want to make a backcast. Touch the rod tip to the surface to make a full rod stroke. In this position, if the rod tip stops in the desired direction, it is possible to make even a vertical cast.
